I found some documents from SAP related to the ODBC connection to HANA, and technically speaking, it´s possible. I'm not sure if the software agreement allows or not this practice for the ERP tables.
In the SAP documentation I also found information about Cluster and Pool table on R/3 and the conversion of such kind of table to SAP S/4. After conversion all table are Transparent. So you can freely query the data from all tables available in the system using an ODBC connection.
I found some posts related to Qlikview and Hana. . Maybe it could help you:
I also attached a documentation from Qlik explaining several options available to connect QlikView or Qlik Sense to HANA.
PS: I didn´t have the opportunity to connect to this database yet.
We were able to connect to SAP 4/HANA and It is very fast (typically in the range of Qlik's in memory speed), but as you mentioned not all types of table are readily available.
We found that direct discovery or on demand generation is the best way to use this technology as the snapshot one has no benefit given the high cost of SAP.
I know that SAP requires you to use the open hub license, although that is typically not enforced if your population is large enough.
We did not yet test yet the pass-through security of the driver.
